Abstract
A processing system includes a sensor module and a determination module. The sensor module is coupled to sensor electrodes and is the sensor module configured to drive the sensor electrodes with sensing signals at a first resonance frequency of the pen. The determination module is configured to obtain, concurrently with the driving of the sensor electrodes, a measurements that are based on effects of the sensing signals, and a resonance of the pen in a sensing region. The determination module is further configured to determine positional information of the pen in the sensing region based on the measurements, and report the positional information.
